Try that : 
program ler_fich;

var d:string[7];
    q:integer;
    p,vt:real;
    fe,fs:text;
begin
assign(fe,'C:\...\artigo.txt');
reset(fe);
assign (fs,'C:\...\resultados.res');
rewrite(fs);
while not eof (fe) do
      begin
      readln(fe,d,q,p);
      vt:=q*p;
      writeln(fs,d,q,vt);
      end;
close(fs);
close(fe);
readln;
end.
